Overview
The RS3236-2.5YF5 is a fixed-output linear low-dropout (LDO) voltage regulator manufactured by Runic Technology. It provides a stable 2.5V output with a maximum continuous current of 500mA. The device operates within an input voltage range of 1.7V to 7.5V and features a typical quiescent current of 40µA. Key electrical specifications include a maximum dropout voltage of 0.6V at full load and power supply rejection ratios (PSRR) ranging from 74dB at 217Hz to 70dB at 1kHz. It incorporates overcurrent protection and thermal overload shutdown for safety. The component is housed in a surface-mount SOT-23-5 package and is rated for operation across a temperature range of -40°C to +85°C.
Feature Summary
- Integrated enable control pin for power management
- Built-in overcurrent and thermal overload protection mechanisms
- Low quiescent current consumption for energy efficiency
- High power supply rejection ratio for noise reduction
Applications
- Battery-powered portable electronic devices

Procurement Notes
Verify the specific suffix YF5 corresponds to the SOT-23-5 package configuration required for your PCB layout. Confirm RoHS3 compliance status if environmental regulations apply to your manufacturing region. Ensure input voltage does not exceed the 7.5V absolute maximum rating during operation. Check datasheet for recommended external capacitor values to maintain stability under varying load conditions.
Selection Notes
Select this component when a fixed 2.5V rail is needed with moderate current capability up to 500mA. It is suitable for applications where input voltage varies but remains above the minimum dropout threshold. Consider the SOT-23-5 package size constraints and thermal dissipation requirements for high ambient temperatures. Compare PSRR performance against other LDOs if sensitive analog circuits are present on the same rail.
